The Development of Model Based Methodologies for Gasoline IC Engine Calibration 2004-01-1466

A series of calibration methodologies have been developed to aid the powertrain engineer in meeting calibration targets throughout the engine development process, i.e. from early engine mapping through to final OBD calibration and vehicle sign off. This paper will present practical examples of the methodologies developed for the base engine mapping phase. The advantages of using design of experiments and advanced statistical modelling to develop empirical models are shown. The models are used to populate the powertrain control module calibration tables as well as for predictive emissions optimisation. The major benefit of the calibration methodologies utilising the model based approach is the ability to evaluate the drive/emissions compromise with no additional testing.
